To all where it concern:

Be it that I, MAXWELL S. HART, a citizen of the United States of America, residing at New Britain, Hartford .SOUIE'LTY, Connecticut, have invented a new and as ful Look, of which the following is a specification.

My invention relates to a lock construction which is particularly useful in connection with sheet metal locker doors as shown herein, but which is not, in its broadest aspect, limited thereto.

My object is to provide a simple compact durable and exceedingly effective locking device.

In the accompanying drawings: Figure 1 is a sectional view of a portion of a door with certain lock parts shown in front elevation and in unlocked position. Fig. 2 is a similar view of the lock parts in locked position. Fig. 3 is a section. on the line 3-3 of Fig. 1. Fig. 4: is a view similar to Fig. 1 showing a modification. Fig". 5 is a section on the line 55 of Fig. i. Fig. 6 is a front view of a part of a door with parts of the lock mechanism shown in Figs. 1 to 3 removed therei'rom. Fig. 7 is an elevation of the inside of a lock case showing its locking .bolt, and key-operated cam. Fig. 8 is a perspective view of the key operated cam.

1 represents a door especially adapted for lockers.= In this instance, the door is made from sheet steel and provided with a hollow stile 2 or border which is extended around the door to form a sunken panel in the center. 3 represents the door casing. In this particular instance the door isprovided with three locking bolts which are arranged to engage the casing 3 at the side, top and bottom. These bolts are indicated respectively at 4, 5 and 6. The door locking bolt 4 is in the form of a hook, which may be withdrawn into the housing formed by the hollow door stile 2, see Figs. 1 and 6,.or may be projected therefrom as indicated in Fi 2. In this last mentioned figure, the bolt 4 is shown as projected through an opening in the door casing so as to be hooked back of the same thus preventing the casing from being pried away from the edge of the door. The door locking bolts 5 andfi are also hidden in the housing or stile 2 and project into suitable keeper plates or openings in the upper and lower parts of the door casing,

Application one Eons 2'7, 1935?. Serial Ia see Fi 6. in o e fornr'oi eonstrnction the a I! hoene' hole t 18 carrier: by an escillating member proted to thedoor 8 while the el are respectively carried by the .ieinher at opposite. sides of the as the part 7 oscillated 5 and 6 will as l and .3, direction, r ig, I sirnole and, s and. control.- means is so compact contained thin door hollow prises a manually this stance t oscillate, and ti ut ized to oncrate This means coinole lock case 9. in mounted to lay referring igs. 1 and 53, it will he seen that the loo case may have a connection with. one of the bolts, that the niovement of the case 9 will move all of the bolts. In the particular form shown the case S has an ofi'set 10 which has an opening or slot 11 therein into which slot may project pin 12 carried by the bolt li. It now the lock case 5) moved from theposition shown in Fig. l to that shown in Fig. 2, the bolt (3 will he moved downwardly, this movement will, through the medi of the part 9, simultaneously proie the bolt upwardly and the hooked bolt i forvmrdly, time looking the door.

The lock rigidly z a low huh or slee z a or plate 1:3.

16 is a suitable handle or knob which in this instance is tubular, the outer end being flared to provide a grip, the inner end Slit ing snugly over the sleeve 1-1 and projecting into the cap 15 to provide a suit-able bearing. The-knob 16 is secured rigidly on the sleeve 14 in any suitable manner as by a screw 17.

18 is a spacer means or washer between the inside of the cap 15 and the outside of the lock case which may provided iii the case is so spaced from the cap 15 to require a spacer element. The turning of the handle or knob '16 will oscillate the look case 9 and hence operate the aforesaid door looking bolts in the manner described.

"iii

19 is a bolt of any suitable type carried hy the lock case 9 and arranged to be operated by a suitable key. This bolt 19 is arranged to be reciprocated from the solid line position to the dotted line position indicated in Fig. 7, and is, of course, provided with suitable guides. 20 is a camerm which projects into a suitable notch 21 in the tail of the bolt 19. This cam arm 20 is located within the lock case and is provided with an outwardly extending shank 22 which carries the disk 23 at its outer end, said disk having a key slot therein, r

24; is a recess in the csm-arm 20 which receives the forward end of a key, the said hey being inserted through the slot in the disk 23 and preferably guided into the slot 24 by a longitudinal groove in the shank 22.

Any suitable tumbler mechanism (shown in dotted lines)- may be provided for bold ing the bolt 19 against movement until said tumblers have been properly positioned. It

should be understood that the particular he operated mechanism for controlling the bolt 19 may be of any appropriate design or construction.

no the particular form shown in the drawings, when the bolt 19 has been fully retracted, as shown in Fig. 7, the turning of the key is checked because the length of the cam arm 20 is such that it cannot be in a clockwise direction to a sufficient extent to-remove it from the notch in the tail of the bolt. Hence, while the door is unlocked, the key remains in the look. When the key is turned back to project the bolt 19 it will thenline up with the notch 25, in the rolled-in edge of the sleeve 14-, and may then be withdrawn.'

When the bolt 19 is projected, as shown in Fig. 2, it will stand between two abutments. In this instance, one abutment is represented by tbe'wall of the cap 15 adjacent to the end of said bolt and the other abutment is the part 26. In this instance the part 26 is a bolt, stud or rivet, utilized to secure the cap 15 in place. 27 indicating a companion bolt used for that purpose. If a proper key is inserted in the key-clot, when the parts stand as shown in Fig. 2, and said hey is turned in a clockwise direction, it will first retract the bolt 19 free ing it from abutment 26 so that a conmanor? lock case 9, whereas in the modification shown in Figs. 4 and 5, I have shown the hooked locking bolt 4 us mounted directly on the lock case 9 and have shown "the locking bolts 5 and 6 as being pivotally connected to wings 99 on opposite sides of said lock case, otherwise the construction and arrangement of parts may be understood to be substantially as shown in the other views.

The stile in which the various parts are located constitutes a hollow housing designed to be located along the freeing edge of the door, and the cap 15 constitutes in effect part of the housing when the parts are assembled. The cap may be and preferably is dished at its rear side so as to be slightly offset from the housing to give the effect of an escutcheon plate, although this is not essential in all cases. I have shown my invention in certain preferred forms-for use in connection with. sheet metal lockers, appreciating that a variety of changes may be made therein for this purpose and other locking purposes without departing from the spirit and scope of this invention.
